Abstract
The effects of mixing of poly(styrene-co-acrylonitrile) (SAN) on the melting and crystallization process of poly(ε-caprolactone) (PCL) were studied under high pressures up to 500 MPa by high pressure differential thermal analysis (DTA). The pressure coefficient of the melting temperature of PCL crystallized at 0.1 MPa was 0.179 K MPa−1 and it slightly increased with decreasing PCL content in the mixture. The phase diagram of the binary mixture in terms of melting and crystallization of PCL was determined under high pressure up to 500 MPa. The exothermic peak of crystallization of PCL in DTA curve shifts to the low temperature side and becomes broad with increasing SAN content in the mixture and this trend is remarkable at elevated pressure.
